Answer 1

Answer:

14 a) In the attached figure, OQ = $\frac{9}{7}$

14 b) x = $\frac{-1}{7}$

Step-by-step explanation:

14 a)

The attached figure shows OP is a unit having seven equal parts.

∴ OP = $\frac{7}{7}$

After P, another Point Q is marked so that PQ is of 2 units length.

∴ OQ = $\frac{9}{7}$

14 b)

$\frac{x + 5}{6} - \frac{x + 1}{9} = \frac{x + 3}{4}$

=> 6(x + 5) - 4(x + 1) = 9(x + 3) [multiplying both sides by 36]

=> 6x + 30 - 4x - 4 = 9x + 27

=> 2x - 9x = 27 - 26

=> -7x = 1

∴ x = $\frac{-1}{7}$
